l COMBINATION COOLER AND FILTER. y

To all whom t may concern;

Be it knovvnthat I, HARRY T. ALLEN, a citizen of the United States of America, residing at Guilford, Connecticut, have'invented a new.l and usefulv Combination Cooler Iand Filter, of which the lfollowing vis a specification.

My present invention-has for its objects to p rovide' as1mple, practical and inexpensive :combined Water cooler and filter which can be readily installed Wherever devsired and which will be thoroughly etlicient and desirable in all respects.

A special object is to insure the cooling of 4a. plentiful supply of thev Water and "to secure a rapid and at the same time thorou h filtration of this cooled water.

nother special object is to prevent drippage from ythe dispensing spout after the How has been cutoff.

, In the accomplishment of the foregoing 'ia-nd ,otherlpobjectsv I employ a coil or an equivalentfor ,cooling the Water and interpose between said cooling coil and the dispensing spout a filter, the iowof Water from the `cooling coil through the filter and out vthrough the dispensing spout being controlled by a suitable valve located preferably between the coil and filter. l

To preventdrippage after the controlling valve is operated to shut oil the flow, I pro- In the accompanying videfa' drip-preventing valve which may be in the form of a spring pressed valve which will open tothe flow ofthe Water' under pressure but will close as soon as the flow lis cut olf and the pressure therefore is no longer present upon it. y

Various other objects and features of the invention Will appear as the specification proceeds.

drawing I have illustrated the-invention embodied in a practical form of ,built-inhousehold type of coolen-and,v ilter=but it will be understood that' :changes: andmodilicationsA may`4 be made Without departing fromy the vtrue spirit `and scope of the-invention. In this-drawing:V j

Patented Alilg. 21, 1917.Y Application ined April 12, 1916. serial No. 90,528. l 'l i i port ,8, this recessor niche in the Wallbeing suliiciently high as indicated, to leave'space enough above the top of, the device for placing ice or other cooling medium inthe cooling compartment of the device.v

The bodyof the device is in the form o1 a double Walled compartment 9, divided in the present instance, by means of a vertical partition 10 into a rear cooling compartment 11, and a forward filtering compartment '12.

The top of the compartment is closed by a suitable cover v14', this'cover inthe ,illus-` tration being arranged to open b v sliding forwardly as indicated in dotted. lines, Fig. 2. The outward sliding movement lof lthis cover may belimited toa position wherein the rearward cooling compartment will be open, this being provided for in lthe illustration bya stop 15 on the under sideof the cover coming into engagement with the upper edge of the vertical partition 10, this stop being pivoted as .indicated'latf16` so as cooling compartment `is,

is connectedv with the filter 2O located inthe f forward filtering compartment 12', this filter being` shown herein as a` receptacle filledV with suitable filtering medium, and supported in said compartment on brackets-21.

Interposed between the cooling coil and the filter, is the controlling, valve 2Q, said valve being herein shown as located in the filter compartment above thevilter .andprovid'edwith Aan operating steml 23 vprojecting out through the front wall of the casing..`

. The cooled .andzi'iltered vwater isdelivered through a suitable dispensing spout'.

lIn use, the ycoolirngcoilcis usuallyjconcoil compartment-is 'kept filled-with iceor other refrigerating medium. The cooling coil is thus kept filled with cooled Water Iunder pressure so that as soon as the controlling valve is operated this Water will be admitted to the filterA and will flow through the same out the dispensing spout. The Water 1s thus cooled when it reaches the filter and-it then only remains for it to be cleansed by passagethroughthe filtering medium'. The filter is preferably made of va capacity sulicient to permit flow of a good z stream of water.

To prevent drippage afterthe controllingj valve-has been actuated, I preferably locate j' a drippage preventing valve betweenthe filter and the dispensing spout, said valve here taking the form of a valve plate 2 5 held by the screw collar 26 between the abutting ends of thepipe sections 27-28,`and provided with a valve opening 29 therein normally closed bythe valve 30, said valve befr ing pivotally supported at 31 and normally held to its valve seat by a spring 32. This valve spring is of suiiicient strength to hold the valve, seated against gravity but not strong 'enough to hold the,Y valve closed against the pressure of the water in the water main.- It follows'ffrom this, therefore, that as soon as the controlling valve is closed and thepressure' therefore is no longer present, that-this valve will close and prevent any drippage from the dispensing spout.

A screen 33 may be provided at this joint 'above the drippage valve to catch and hold j any of the filtering material that may escape the first screen 34 and to prevent clogging of this valve.

A door'35 may be provided lin the front of the casing tov admit access to this drip preventing valve. i.

The filter is preferably made readily removable from the casing for the purpose of cleaning or renewal of the ltering material.

For this reason the valve operating stem 23- is preferably made with a joint 36 and the "filter is made readily disconnectible from 'the coolin coil as by means of a suitable coupling 3 It will be apparent that when the coupling 37 is opened andthe valve stem 23 is disconnected and the coupling 26 is undone, that the filter as a whole may be llifted out of the filtering compartment.

The filter casing is preferably provided with a filling opening closed by a removable plug 38. When this plug is removed the ventire contentslof the filter casing may be dumped out@ and cleaned or renewed, as the case may bev The upper 'end ofthe cooling coil may be connected by a coupling 39 to the opposite end of the sleeve 40 with which the coupling 37 connects. This construction makes it possible to disconnect either the cooling coil or the filter without disturbing the one which is not disconnected.

The forwardly slidingI cover 14 may be guided in a suitable guide-wayin, as ind cated in Fig. 2.

From the foregoing, it will be seen the invention is adapted for ready installer' tion in residences, oliices, etc., without mak-iii lng any changes -in the .water connections, the only thing necessary being a connection with the water mainfand it will further be seen that when installed in a wall as illustrated, the device is of the way. What I claim is:

1. A combined liquid cooler and, ilter ipconspicuous and out comprisingv a casing, a cooling coil in said casing adapted for connection at its inlet endwith a liquid s upplyvmain, alfilter in the casing connected at one endwith the outlet end of the cooling coil, a control valve outlet end of the cooling coil and the inlet end of the filter, said control valve having an. exposed manually operable handle projecting through the casing, and an exposed freely-delivering dispensing spout connected with the outlet end of the filter and projectinterposed in' the connection between the ing Athrough the casing, whereby, upon operation ofthe exposed valve handle, cooled liquid from the coolingcoil will be ad-` ensin los all whereby uponoperation of said exposed' handle liquid from the main liowing through the cooling coil will be admitted to the filter and will be delivered by the lter through. 4

the vopen dispensing spout and an automatie drip preventing valve connected with said freely discharging dispensing spout to. c

thereby prevent drippage from the `filter' after the manually controlled valve has been operated.

3. A combined lter-and cooler comprising a casing having la partition dividing the `same into front and rear compartments, a

cooling coil located in the rearcompartment, a filter located in the front compartment, a dispensing spout connectedto said filter and a valve interposed between the cooling coil and the lter and having van operating stem projecting through the front of the casing.
